ADVERTISING APPARATUS Application filed November 14, 1927, Serial No. 233,256, and in France November22, 1926..

Advertising devices are already known in which the advertising objects, such as signs or pictures are mounted upon rods which are assembled in magazines and thesaid objects are caused to travel in succession before the public eye. 3 a

- The present invention relates to an apparatus of this class which affords various practical advantages for advertising purposes. v Y

I In my said apparatus, suitable racks or the like, are employed to take up each sign or picture and to transport it from one magazine to another; to the said racks is'preferably .15 given a straight reciprocating motion by means of motor power or by hand. I prefer to employ a first set of racksto transport the said rods from a first magazine to a second,

and a second set of racks to convey the'rods 2 from the second magazine to the first; the said racks are preferably connected together by flexible means such as, a-chain coacting with supporting pulleys.

' I will describea practical construction for the mechanism actuating the said racks as follows: Y

The motor drives'indirectly a wheel which carries a toothed sector at its periphery;

which sector engages at different times with two respective pinions, and each pinion indirectly drives a corresponding rack.

The magazines may be disposed as follows:

The rods are placed upon a stationary toothed member; adjacent this member, a'

movable toothed member, which is given a reciprocating motion, raises thesaid rods and causes them to move forward, tooth 'by tooth, towards the outlet of the magazine.

The reciprocating motion of the movable 40 toothed member may be obtained by means of an eccentric or the likeadapted to give the said member a vertical reciprocating motion, while a second eccentric (or cam) or the like givesit another lateral reciprocating motion spaced at 90 degrees from the first.

By way of example and for the proper understanding of the following description, I have represented in the appended drawings an embodiment of the present invention.

Fig.1 is a sectional and elevational \view i of the apparatus.

Fig. 2 is a detail viewof the upper magazine. a i

In the example herein represented, the

mechanism as a whole is housed ina case 1 whose two sides serve to display the signs or pictures, each side comprisingtwo apertures or windows 2, placed respectively at theupper and the lower part,- thus providing four The advertising signsare mounted upon rods 23 (Fig. 2) whereby'they. may be displaced or stowed away in the manner to be further disclosed.

windows in all for the display of'the signs.

. Y i 65. The mechanism comprises, two simllar de Vices andonly one device is shown on Figure 1. Each device comprised twoparts, firstly magazines or storage devices, and secondly a set of racks which are adapted to transfer the advertisements successively magazine to theother. p H

p 1. Rack mwement The device is operated by a chain 40' drivis keyed a pinion 6jcoact-ing with a, gear wheel .50; said wheel carries atone side-and for about the periphery a toothed sector 52 which alternately engages the gear wheels 53 and5/1. p 59 by means of the gearing 5556 57.58. .The wheel 5 1 actuates the other rack 63 by means of the gearing 6162. ,A pinion engages both, gear wheels 56 and 60.,

The wheel 53 actuates the rack Each rack is guided by rollers 6 land is thus respectively held against the driving pinion 58 or 62. A chain 65 attachedto' the top of the racks is disposed upon the sup porting pulleys 66-67 2. Movement of the 'l nwgazi/rws or storage I I I dewz'ces v Thesaid devicesare operated by'the pinion 7 6 'and the chain whichdrivesthe pulleys 8 and 9. The chain 46disposed on the chain wheel 12 drives the upperdevice, a'nd'the v chain 68 drives the lower device. Fig. 2shows on alarger scale, the, devlce contained in the upperv magazlne; it comprises a stationary 75 mg. a chain wheel 4:; upon the wheel shaft 1 plate 14 provided on the upper edge with the teeth 15. A movable toothed plate 16 is held against the stationary plate 14- by the stationary guides 17.

The movable toothed plate 16 is given a vertical reciprocating motion in the following manner. The lower edge of the plate 16 is controlled by a lever i2 at whose middle part is disposed a steel ball 48 coacting with an eccentric 18 mounted on the shaft of the gear wheel 13, which is driven by the chain 46. The movable plate 16 is also given a lateral motion, and for this purpose a wheel 44 keyed to the shaft of the wheel 13, carries a finger 19 coacting with the levers 20 which are pivoted to the fixed plate 14 and whoseforkshaped ends coact with the studs 21 secured to'the toothed plate 16; said studs are movable in straight slots 22 provided in the plate The operation of the'apparatus is as follows: a

Inthe position shown in Figure 1 the wheel turns according to the arrow 70, and the toothed sector 52 will now'engage the pinion '53, so that the pinion '58 rotating in "the direction of the arrow 61 will raise the rack 59. During the same time, the wheel 56 .engaging the pinion 75, causes the wheel 62 to rotate by means of the wheels and 61, so that the rack 63 goes down.

The rack 59 lifting, the fork '69 provided at the upper part of the said rack, raises the rod 23 situated in the last .tooth of the plate of the lower magazine. When the said rod 23 approaches the'upper magazine, it meets the stud 72, and pushes it upward, and after the rod is passed, the stud 72 will return to its original position, so that when the rack 59 descends, the rod will be caught by the stud 72 and thus sending it to the first tooth of the plate '15. The sign will hence be in full view to the public through the window '2.

The alternate motion of the toothed member 16 due to the eccentric 18 and the arm 19 will cause the rod 23 to move forward tooth by .tooth and during this time other cards or signs will successively take the place of one another. Duringthis'time the wheel 50 continues to rotate in the direction of the arrow 7 '70,. and at a lcertain moment the toothed sector 52 will engage the pinion 54, so that the wheels are turning in an opposite direction, as mentioned previously, thus causing the rack 63 to rise and the rack 59 to descend. 'As'the fork 73 ofthe rack 63passes the upper plate, the point of the fork 73 receives the I rod 23 from .the last tooth of the plate 15.

The sector ,52 then engages the pinion 53, so

that the rack 59 will again rise, as stated,

' 74of the fixedtoothedplate in the lower short-er than the corresponding lower stationary plate, since the upper stationary plate must leave a sufficient spaceforthe rise and descent of the rod 23. The toothed part of the movable plate 16 has one tooth less than the fixed toothed partin the lower and upper magazine.

With the said apparatusI obtain an advantage which consists in the fact that the interior may be lighted permanently or otherwise, so that the apparatus will be adapted for day or night uses.

Obviously, the advertising ob ect suspended from the said rods may be replaced by any other suitable objects -or articles such as textile fabrics, lace, or the like.

In'the stationary plate 14 of the upper mechanism I employ in all cases a tooth which is not utilized, as also in thelower mechanism, whereby the advertising object may be readily-changed. P

Leaving empty spaces between the rods, it 'is'possible to have duringaspecified longer time the obj ectsin view of the public, with out "readjusting the-mechanism.

It will be noted that this apparatus can have four signs shown'at the same time.

Having now particularly vdescribed my invention and in what manner the same isto be performed, I claim as my inventionrzl 1. Publicity apparatus for presenting ob jectssuspendedon rods, comprising an upper magazine and a lower magazine in which the ends of the rods bear on fixedtoothed mem bers, movable toothed members arranged parallel along each fixed toothed member, an eccentric actuated by a chain directly actuating each movable 'toothed member, two

groupsof vertical racks, one in front, the

other behind the magazines, and a toothed sector 'in continuous rotation, cominginto engagement on the one hand with the/pinion which controls the movement of'the racks in one direction, and on the-other with the pinion which controlsthe movement ofthe racks in the opposite direction. I 4

2. An apparatus as claimed in claim-1, in which each of the mechanisms actuating the racks comprises a driving wheel, a toothed sector mounted thereon, two pinions engaging said sector at different times, and gearing disposed between each pinion and one of the racks.

which the mechanism actuating the movable toothed member, comprises an eccentric imparting to said movable member a vertical reciprocating motion and a rotating finger imparting to the said movablemember a horizontal reciprocating motion. v
